What the swell looked like at creation
This swell was a 300 degree swell in the tail of the Aleutians.
It mostly sat and span for 12-24 hours, then broke up. It was
about 976 mBar, but had a very tight isobar gradient close to its
center. Swell hit SF at 5 foot on the first day. SW winds came
up and roughed up the sea surface for the rest. Second day was
about 4 foot 12 sec. Swell 3, incase you are wondering,
occurred in the same place and was a little smaller, about 2
days earlier. Its tail can be seen in these energy plots.
